  1. 1. Antimony diffusion from polyester textiles upon exhaust dyeing

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Shah Miran Patwary; [2017]
    Keywords : PET polymer; polymerization; di-antimony tri-oxide; polyester textiles; exhaust dyeing; antimony diffusion; waste water; health safety; environmental issues;

    Abstract : In recent years, environmental authorities in Sweden are reporting about high content of antimony in waste water that is discharging from polyester textile dyeing industries. It is known from available scientific publications that, antimony and its compound is harmful for both human and environment. READ MORE

  3. 2. Dynamics of Mitochondria and Actin Cytoskeleton Interactions in Budding Yeast.

    University essay from Lunds universitet/Tillämpad biokemi

    Author : Martina Pola; [2013]
    Keywords : Mitochondria; Actin cables; Cytoskeleton; Cell division; Glucose repression; Arp2 3 complex; ARC15; AIM7; Biology and Life Sciences;

    Abstract : In the budding yeast, S. cerevisiae, mitochondrial distribution involves movements of the organelle from the mother cell to the bud (anterograde movement) and from the bud to the mother (retrograde movement). READ MORE

  4. 3. Study of ethylene/propylene polymerization, using a 4th generation Ziegler-Natta catalyst: Effect of external donor and feed ratio on polymerization

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Seyedeh Shafagh Dehghani; [2012]
    Keywords : Ziegler-Natta catalysts; Electron Donor; Copolymerization; Polyolefins;

    Abstract : A fourth generation multiple site Ziegler-Natta catalyst was used to synthesize ethylene and propylene homo-and copolymers in the presence of hydrogen. This type of catalysts produce polymers with broader molecular weight distribution (MWD), chemical composition distribution (CCD) and stereoregularity than other coordination polymerization catalysts since it has more than one active site.

  5. 4. Impact of degree or Polymerization of Fiber on Viscose Fiber Strength

    University essay from Högskolan i Borås/Institutionen Textilhögskolan

    Author : Shoaib Iqbal; Zuhaib Ahmad; [2011]
    Keywords : viscose; viscose fiber; fiber strength; degree of polymerization; dp; regenerated fiber; regenerated cellulose fiber;

    Abstract : The aim of the study was to find out the relationship between the DP and the tensile properties of different regenerated cellulose fibers. During the process to make regenerated cellulose fibers from wood, the reduction in DP of cellulose is a necessary process to enable fiber extrusion. READ MORE

  6. 5. Applications of Ultra Smart Textiles in Sportswear and Garments

    University essay from Högskolan i Borås/Institutionen Textilhögskolan

    Author : MUHAMMAD ZAHID NAEEM; SHAHNAWAZ MEHMOOD; [2010]
    Keywords : phase change material; smart textiles; paraffins phase change material;

    Abstract : Smart textiles especially Phase Change Materials (PCMs) are getting attention because these materials can provide regulation of wearer’s body climate and provide comfort in the temperature fluctuations during the physical activity like sports. These materials have the advantage of latent heat energy storage that can absorb and release high amount of energy over a narrow temperature range around the human’s body temperature to provide thermal comfort.
